Mazda RX-8 with a Honda K20

I came across this 2005 Mazda RX-8 with a Honda K20Z4 motor while browsing Youtube. The build thread is in Polish but from what I could make out the car uses two ECUs and still has traction and stability control. The owner plans on turbocharging the motor with a GT3071R to reach 400+ horsepower.
